Tyson Trish/The RecordThe NJ Transit train station at the Meadowlands. Trains will run to the complex tonight to accomodate the thousands expected for a Talmud study celebration.

EAST RUTHERFORD — MetLife Stadium becomes the world’s largest synagogue tonight, when it hosts 90,000 Orthodox Jewish women and men who celebrate the completion of the latest cycle of Talmud study.

Because the huge crowd will descend on one of America’s most congested locations during the middle of the evening rush, New Jersey transportation agencies are scrambling to make sure traffic and transit flows.

MetLife Stadium has handled enormous audiences for National Football League games and U2 concerts, but this event brings its own special transportation concerns.

“This is occurring during a rush-hour period on a Wednesday, so there will be a significant impact on transportation services within not only the area around the Meadowlands, but also on our rail service going through Secaucus,” NJ Transit spokesman John Durso Jr. said today.

NJ Transit is running trains from Secaucus Junction to the Meadowlands complex beginning at 4 p.m., and the last train rolls out of the complex no earlier than 12:40 a.m., officials said.

The 7 p.m. event celebrates the “Daf Yomi” (Page a Day) program. In all, 2,711 pages of the Talmud have been studied over 7 1/2 years, and participants from as far away as Australia are expected to visit New Jersey tonight, according to Agudath Israel of America.

Beginning in the afternoon, motorists should expect heavy congestion on routes to and from the stadium, officials from the state Department of Transportation said.

To facilitate travel, the DOT will keep open lanes of Routes 3, 17 and 120 that usually would be closed for construction.
